The halogen family is group 17 and it has 5 elements. They are:
Fluorine, F, Gas
Chlorine, Cl, Gas
Bromine, Br, Liquid
Iodine, I, Solid
Astatine, At, Solid
Halogen means "salt forming." All of the halogens are very reactive. The uncombined elements are dangerous to humans.
This is a pictrue of bromine.
This is a picture of the periodic table of elements.
Chemical Properties:
All very reactive
Burns Skin (Bromine)
Carbon and Flourine combined make non-stick coating on cookware.
Physical Properties:
Fluorine: a pale yellow
Chlorine: a yellow greenish
Bromine: a brown redish
Iodine: a dark violet
Astatine: none
Common Uses:
Bromine: In medicines, fumigants, dyes, and water purification pounds.
Fluorine: air conditioning, refridgeration, and toothpaste.
Astatine: none
Iodine: plants and animals need trace amounts of iodine for normal growth, and also used for it's antibacterial qualities.
Chlorine: many cleaning products as well for disinfecting pool and drinking water.
This is example of Fluorine (tooth paste.)
Intresting Facts:
flourine is the most electromagative and the most reactive chemical element.
Hydrogen and flourine react with explosive violence.
Flourine is good for very explosive reactions.
Iodines name originates from the greek word Iodes meaning Violet.
